The correct answer is **C. I only.**
When butter melts, it undergoes a physical change. The butter changes from a solid to a liquid due to the heat, but it does not create a new substance; it remains butter (just in a different state). Therefore:
- **I. It is a physical change.** - True
- **II. It makes a new substance.** - False
- **III. It is a chemical change.** - False
Thus, only statement I is true.
